Question

Question 6: Cell division is central to regeneration and growth of tissues, a. What subcellular process is essential for all cells to divide? Why do you think this process is conserved across all eukaryotic cells? b. After the chromosome complement has been separated, the remainder of the cell must separate. What do we term this phase and what cellular components must divide at this stage? c. How is the final separation of daughter cells achieved in animals vs plants? (Hint: What process must be completed in plant cells that is not required in animal cells) d. How can cell division be disrupted chemically and what fundamental subcellular structure is normally targeted by these cell division blocking agents?

Answer 1

Answer a:)

Mitosis is the subcellular process that is conserved and essential for all cells to divide. This is the process by which a cell can divide into its own type with the ability to conserve its genetic material throughout generations. All eukaryotic cells possess Mitosis and hence it is a conserved subcellular process among them.

Answer b:)

This is called cytokinesis that is occurred after the completion of mitosis. The cytokinesis is processed by which cytoplasm, organelles, and cellular membranes are equally divided into two cells.

Answer c:)

The final step of the cytokinesis in the plant cell is the transformation of a cell plate into the cell wall. The animal cells do not have a cell plate during mitosis as they have cleavage furrow.

Answer d:)

Various chemicals called mitotic inhibitors are capable to stop cell division. To stop the cell division, these inhibitors distorts the formation of microtubules that are essential to perform cell divisions successfully.
